Aether Refinery

Card text

If you would get one or more {E} (energy counters), you get twice that many {E} instead.

{T}: You get {E}, then you may pay one or more {E}. If you do, create an X/X black Aetherborn creature token, where X is the amount of {E} paid this way.

Avaati Vya's invention stabilized raw aether, but even she didn't know it would also create life.

Official rulings

The 8 most recent official rulings for Aether Refinery, newest first.

• 2024-06-07 If two or more effects attempt to modify how many {E} you get (or how many counters you would get), you choose the order to apply those effects, no matter who controls the sources of those effects.
• 2024-06-07 Some triggered abilities that state that you "may pay" a certain amount of {E} describe an effect that happens "If you do." In that case, no player may take actions to try to stop the ability's effect after you make your choice. If the payment is followed by the phrase "When you do," then you'll choose any targets for that reflexive triggered ability and put it on the stack before players can take actions.
• 2024-06-07 If a spell or ability with one or more targets states that you "may pay" some amount of {E}, and each permanent that it targets has become an illegal target, the spell or ability won't resolve. You can't pay any {E} even if you want to.
• 2024-06-07 Energy counters are a kind of counter that a player may have. They're not associated with any specific permanents.
• 2024-06-07 Keep track of how many energy counters each player has. Potential ways to track this include writing theme down on paper or using dice, but any method that is clear and mutually agreeable is fine. (At higher levels of tournament play, dice may not be allowed for tracking counters that players have.)
• 2024-06-07 If an effect says you get one or more {E}, you get that many energy counters. To pay one or more {E}, you lose that many energy counters. You can't pay more energy counters than you have. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.
• 2024-06-07 Some spells and abilities that give you {E} may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't get any {E}.
• 2024-06-07 Energy counters aren't mana. They don't go away as steps, phases, and turns end, and effects that add mana "of any type" can't give you energy counters.
